- Applied mechanics
Applied mechanics is a branch of the
physical sciences and the practical application of mechanics. Applied mechanics examines the "response of bodies (solids and fluids) or systems of bodies to external forces". Some examples of "mechanical systems" include the flow of a liquidunder pressure, the fracture of a solidfrom an applied force, or the vibration of an ear in response to sound. A practitioner of the discipline is known as a mechanician.
Applied mechanics, as its name suggests, bridges the gap between physical theory and its application to
technology. As such, applied mechanics is used in many fields of engineering, especially mechanical engineering. In this context, it is commonly referred to as engineering mechanics. Much of modern engineering mechanics is based on Isaac Newton's laws of motion while the modern practice of their application can be traced back to Timoshenko, who is said to be the father of modern engineering mechanics.
Within the theoretical sciences, applied mechanics is useful in formulating new ideas and theories, discovering and interpreting phenomena, and developing experimental and computational tools. In the application of the
natural sciences, mechanics was said by the American Nobel Prize-winning chemist Gilbert N. Lewisand the American physical chemist Merle Randallto be complemented by thermodynamics, the study of heat and more generally energy, and electromechanics, the study of electricityand magnetism.

Mechanics in practice
As a scientific discipline, applied mechanics derives many of its principles and methods from the
Physical sciences(in particular, Mechanicsand Classical Mechanics), from Mathematicsand, increasingly, from Computer Science. As such, Applied Mechanics shares similar methods, theories, and topics with Applied Physics, Applied Mathematics, and Computational Science.
As an enabling discipline, applied mechanics has received impetus from the study of natural phenomena such as orbits of planets, circulation of blood, locomotion of animals, crawling of cells, formation of mountains, and propagation of
seismic waves. Such studies have resulted in disciplines such as celestial mechanics, biomechanicsand geomechanics.
As a practical discipline, applied mechanics has also advanced by participating in major inventions throughout history, such as buildings, ships,
automobiles, railways, petroleum refineries, engines, airplanes, nuclear reactors, composite materials, computers, and medical implants. In such connections, the discipline is also known as "Engineering Mechanics", often practiced within Civil Engineering, Mechanical Engineering, Construction Engineering, Materials Science and Engineering, Aerospace Engineering, Chemical Engineering, Electrical Engineering, Nuclear Engineering, Structural engineeringand Bioengineering.
Applied mechanics in engineering
Typically, engineering mechanics is used to analyze and predict the acceleration and deformation (both elastic and plastic) of objects under known forces (also called loads) or stresses.
When treated as an area of study within a larger engineering curriculum, engineering mechanics can be subdivided into
Statics, the study of non-moving bodies under known loads
*Dynamics (or kinetics), the study of how forces affect moving bodies
Mechanics of materialsor strength of materials, the study of how different materialsdeform under various types of stress
*Deformation mechanics, the study of deformations typically in the elastic range
Fluid Mechanics, the study of how fluids react to forces. Note that fluid mechanics can be further split into fluid statics and fluid dynamics, and is itself a subdiscipline of continuum mechanics. The application of fluid mechanics in engineering is called hydraulics.
Continuum mechanicsis a method of applying mechanics that assumes that all objects are continuous. It is contrasted by mechanics and the finite element method.
